rex infernus easter egg steps: Step-by-Step Walkthrough

The rex infernus easter egg steps follow the final Round-Based Zombies map in Black Ops 7. The Main Quest centers on cleansing the Shadowsmiths’ places of power, reaching the Warden’s inner sanctum, and confronting the force behind the collapsing reality.

Rex Infernus launched with Season 05 Reloaded on August 20, 2026, and the Main Quest became available at 9 AM PT. The map continues the story established across Ashes of the Damned, Astra Malorum, Paradox Junction, Totenreich, and Kowakujō.

The opening route is relatively clear:

1. Survive the opening holdout in the abandoned house.
2. Answer the ringing phone and enter the portal route.
3. Place the World Seed at the Nexus Forge.
4. Defeat two Dread Skulls and return their flames.
5. Activate Pack-a-Punch.
6. Upgrade the flame into Astral Fire.
7. Solve the Nyxara Sanctuary beam puzzle.
8. Gather three Warden’s Blight parts from the Silent Area.
9. Complete the randomized Dravakar pillar puzzle.
10. Assemble the Warden’s Blight Crossbow.

Begin in the abandoned house and activate the opening objective, “Holdout in Her House.” Zombies enter from multiple directions, so use the room layout carefully and avoid becoming trapped near the weapon racks.

The house includes several useful early resources, including a GobbleGum machine, a Quick Revive upgrade, and two wall-mounted weapon racks. The piano can also be interacted with, although its purpose belongs to a later puzzle sequence.

The second Dread Skull leads toward Caltheris Main Chamber, where a large Titan appears after the skull is destroyed. Its ground-smashing attacks can punish players who stay in one position, so keep moving while completing the return route.

With Pack-a-Punch active, begin the Wonder Weapon route. The weapon is called the Warden’s Blight Crossbow, and its construction requires a chain of objectives across the Nexus Forge, Dravakar’s Main Chamber, Nyxara’s Sanctuary, and the Silent Area.

First, upgrade the flame used during the Pack-a-Punch sequence. Use your grapple to collect a floating purple orb and carry it back to the Nexus Forge. Place the orb into the forge and activate the mechanism again. The flame changes from purple to blue, creating Astral Fire.

Next, travel to Dravakar’s Main Chamber and search above the entrance from inside the room. Grapple or wall-jump to the upper platform. A breakable wall section on the right hides the Purple Crystal. Use a grenade or another explosive to open the wall and collect the crystal.

Take Astral Fire to Nyxara’s Sanctuary and reach the large eye at the end of the temple. Shoot the eye with Astral Fire to begin the light-beam puzzle.

Several purple crystals around the chamber can be rotated with the grapple. Redirect the beam from one crystal to another until it reaches the location where a crystal is missing. Grapple to the empty slot and place the Purple Crystal from Dravakar’s chamber. Continue rotating the remaining crystals until the beam reaches its final destination.

A hidden room opens after the beam puzzle is completed. Inside, interact with the roots of the strange tree and sacrifice some health to feed it. Once the tree produces a fruit, eat the fruit to enter the Silent Area.

The three parts are associated with corpses in different parts of the forest:

• Cave: Travel toward the far end of the Silent Area and inspect the dead body near the cave.
• Rock: On the next visit, search the middle section for a corpse beside a rock.
• Burned Cabin: On the third visit, look near the burned cabin for a corpse and a glowing wooden plank. Melee the plank to reveal the final part. Melee Macchiato may be required if a normal melee attack does not trigger it.

Advance to the next round between visits, then return to the tree and eat another fruit to enter the Silent Area again.

After collecting all three parts, return to Dravakar’s Main Chamber. The final construction step uses a pillar puzzle with symbols including the Star, Moon, Runner, and Galaxy.

The solution is randomized between matches, so there is no universal combination to copy. Instead, listen to Dravakar’s dialogue and inspect the writing that appears on the wall. The riddle explains how the symbols relate to each other.

For example, a clue stating that the Star follows the Moon means the Star pillar should be rotated so it points toward the Moon. Apply the same logic to each clue rather than guessing from a fixed online solution.

When all pillars point in the correct directions, an opening appears above the chamber. Grapple through the hole in the ceiling to reach the Wonder Weapon build location. Interact with the station after collecting all three parts to assemble the Warden’s Blight Crossbow.

At this point, the confirmed walkthrough reaches the weapon assembly stage. The supplied quest information does not verify the later objectives, boss mechanics, or final arena sequence, so avoid treating unconfirmed steps as established solutions.

The Warden is confirmed as the final confrontation of the Black Ops 7 Zombies storyline, but the supplied walkthrough does not provide verified instructions for the final boss phases. Prepare the Crossbow and a strong secondary weapon before advancing beyond the confirmed construction route.

Rex Infernus also introduces two spider-themed enemies. Deathspinners are fast enemies that can fire web projectiles, slowing players while regular zombies close in. The Web Mother is an Elite enemy that can scream, lunge, cover areas with damaging webbing, and cocoon zombies.

The map-specific Titan Trap summons a massive force that pounds the ground, pulls nearby zombies into the attack, and destroys them. Keep clear of the impact area because the Titan can also damage players.

Completing the quest before Directed Mode arrives provides an additional Calling Card variant. The map also includes separate Intel and Mastery objectives, including Audio Logs, Documents, Artifacts, and Pack-a-Punch camouflage challenges.
